Product details

It's rated for a 0.75 kW motor at 400 V, with a CLASS 10 trip curve that coordinates with standard induction motor startup (clears within 10 seconds at locked-rotor current). The 24 VDC control supply (20.4 to 28.8 V range) is common for safety circuits and PLC-driven panels. It carries four digital inputs and one digital output, so it can take direct commands from a controller or sensor string without an extra I/O block.

The enclosure measures 159 mm deep, 294 mm wide, and 215 mm high — a compact footprint for a reversing starter with integrated I/O. The IP65 rating means the housing seals against dust and low-pressure water jets, making it suitable for food processing lines, conveyor washdown zones, or outdoor installations under a canopy. Main power connects through a HAN Q4/2 plug (ISO 23570), and the AS-Interface bus connection uses an M12 plug for addressing.

If you're running a high-inertia load (centrifuge, large fan) that needs a longer acceleration time, CLASS 10 may be too fast — but for pumps, compressors, and conveyors it's the right call. The 0.75 kW rating at 400 V (0.7 hp at 460/480 V) sets the maximum motor size this starter can handle. The 24 VDC coil is inherently safer for control circuits and compatible with most PLC outputs, but verify your control transformer can supply the inrush if you're ganging multiple starters.

Frequently asked questions

What are the key dimensions for panel fit?

The enclosure is 159 mm deep, 294 mm wide, and 215 mm high. It mounts via screw fixing and can be installed vertically, horizontally, or flat.

What is the motor power rating and trip class?

It is rated for 0.75 kW at 400 V (0.7 hp at 460/480 V) with a CLASS 10 trip curve, meaning it coordinates with standard induction motor startup.

What is the supply voltage and I/O count?

The control supply is 24 VDC (20.4 to 28.8 V range). It has four digital inputs and one digital output for direct connection to a controller or sensor string.
